An emu is a large, flightless bird that is native to Australia. It is the second-tallest living bird after the ostrich and the largest native bird in Australia. Emus are soft-feathered, brown, and have long necks and legs. They can reach up to 1.9 meters (6 ft 3 in) in height and can run up to about 30 miles (50 kilometers) per hour. They are omnivores and forage for a variety of plants and insects, but have been known to go for weeks without eating. They drink infrequently, but take in copious amounts of water when the opportunity arises. Emus are an important cultural icon of Australia, appearing on the coat of arms and various coins. The bird features prominently in Indigenous Australian mythology. Emu meat is considered a red meat by the US Food and Drug Administration because its red color and pH value approximate that of other red meats.
